In geology and mineralogy, the term "carbonate" can refer both to carbonate minerals and carbonate rock (which is made of chiefly carbonate minerals), and both are dominated by the carbonate ion, CO 32–.
Carbonate, any member of two classes of chemical compounds derived from carbonic acid or carbon dioxide (q.v.). The inorganic carbonates are salts of carbonic acid (H2CO3), containing the carbonate ion, CO23-, and ions of metals such as sodium or calcium.
The carbonate ion is a polyatomic anion composed of one carbon atom and three oxygen atoms, with the chemical formula CO32- and an overall charge of −2. It readily combines with metal cations to form ionic compounds known as carbonates, which are salts of carbonic acid (H 2 CO 3). [1-4]
Carbonate is a polyatomic anion with the formula C O 3 2 and has a trigonal planar molecular structure which consists of a carbon atom surrounded by three oxygen atoms.
In chemistry, a carbonate is an ion consisting of one carbon and three oxygen atoms or a compound that contains this species as its anion. The molecular formula for the carbonate ion is CO 32-.
The meaning of CARBONATE is a salt or ester of carbonic acid. How to use carbonate in a sentence.
A carbonate is a chemical compound that contains the carbonate ion (CO₃²⁻). This ion consists of one carbon atom bonded to three oxygen atoms. Carbonates are formed when carbon dioxide reacts with metal oxides or hydroxides, a process that occurs both naturally and industrially.
The two carbonates used commercially in the largest quantities are sodium carbonate and calcium carbonate. In the United States, sodium carbonate is extracted from the mineral trona, Na 3 (CO 3) (HCO 3) (H 2 O) 2.
